Course Contents:
The first part of the lecture will give an overview of Terahertz sources and detectors with the focus on continuous-wave Terahertz generation and detection with semiconductor-based devices. Terahertz detection and generation will be discussed in detail for two types of highly important devices: Schottky diodes (mixers, multipliers and rectifiers) and photomixers (photo-diode based and photoconductive). The first part will conclude with an exercise where performance parameters of the discussed devices will be derived for experimentally relevant cases.
The second part of the lecture is focussed on sensors and their applications using the THz systems presented in the first part. Different sensor concepts based on functional layers (e.g. immobilized antibodies, ssDNA), Metamaterials, periodic structures, resonators and transmission lines will be introduced and their applications in the biomedical area will be discussed. The last day will be used for a lab tour showing our measurements facilities and hands-on experiments.
